Abstract

The invention relates to a high-wear-resistant and heavy-corrosion-protection ceramic coating which is prepared by the following raw materials by mass percent: 24% of epoxy resin, 58% of filler, 3% of pigment, 10% of solvent and 5% of curing agent, wherein the solvent consists of 6% of butanone and 4% of isopropanol, and the curing agent consists of 2.5% of 2-methylimidazole and 2.5% of methanol. The ceramic coating has the benefits that an adhesive force of the ceramic coating reaches 11-14Mpa; the hardness is 6H; the ceramic coating has high wear resistance and high acid, alkali and salt resistance; the service life of the ceramic coating is over 10 years in harsh corrosion environments such as a chemical atmosphere and a marine atmosphere; the solid content is close to 90%; 10% of volatile matter is a solvent which does not harm an environment; the ceramic coating is constructed without a primer and sprayed directly; spraying is conducted twice; a film is formed once; an interval between twice spraying is 30min; the thickness of the film can reach 600 micrometers; and the construction cost is lowered.

Description

The heavy anticorrosion ceramic pain of a kind of high abrasion

Technical field

The present invention relates to the chemistry painting industry technical field, relate in particular to the heavy anticorrosion ceramic pain of a kind of high abrasion.

Background technology

In the energy and Financial cost consumption of the industrial circles such as building materials, thermal power generation and metallurgical mine, because the expense that wearing and tearing produce is occupied the quite large proportion that obtains.Take cement industry as example, and account for 50 ~ 55% of total shutdown the stop time caused because of wearing and tearing, and can the equipment attrition problem has become a cement production enterprise do one of vital factor of operation well.Therefore, improve the wear resistance of industry correlated parts, reduce the consumption of high-abrasive material, extend the work-ing life of high-abrasive material, to improving equipment operation efficiency, reduce production costs, save energy is significant.But the wear resistance of current traditional abrasion resistant anticorrosive paint, preservative property are all unsatisfactory, toxic substance content is large, uses complex steps.

Summary of the invention

The purpose of this invention is to provide the heavy anticorrosion ceramic pain of a kind of high abrasion, to overcome the currently available technology above shortcomings.

The objective of the invention is to be achieved through the following technical solutions:

The heavy anticorrosion ceramic pain of a kind of high abrasion, its raw material by following mass percent is made: 24% epoxy resin, 58% filler, 3% pigment, 10% solvent and 5% solidifying agent; Wherein, described 10% solvent is comprised of 6% butanone and 4% Virahol, and described 5% solidifying agent is comprised of 2.5% glyoxal ethyline and 2.5% methyl alcohol.

Further, described filler is 10 micron-class superfine glass powders.

Further, described pigment is titanium dioxide, red iron oxide, graphitized carbon black or organic red.

Beneficial effect of the present invention is: this product sticking power reaches 11-14Mpa, and hardness 6H has high-wearing feature, and acidproof alkali salt ability is strong, even in the corrosive environment of the harshnesses such as chemical atmosphere, marine atmosphere, the life-span is more than 10 years; It is all the solvents without harm to environment that solid content approaches 90%, 10% volatile matter; Construction is without priming paint, direct spraying; Twice spraying, one-pass film-forming; Spray 30 minutes, interval twice, be coated with thickness and can reach 600um, reduced construction cost.

Embodiment

The heavy anticorrosion ceramic pain of the described a kind of high abrasion of the embodiment of the present invention, this coating is made by 24% epoxy resin, 58% filler, 3% pigment, 10% solvent and 5% solidifying agent; Described solvent is comprised of 6% butanone and 4% Virahol; Described solidifying agent is comprised of 2.5% glyoxal ethyline and 2.5% methyl alcohol, and above per-cent is mass percent; Described filler is 10 micron-class superfine glass powders; Described pigment is titanium dioxide, red iron oxide, graphitized carbon black or organic red.

During concrete the making, getting 58 kilograms of particle diameters is that 10 micron-class superfine glass powders are as filler; Using joining in 24 kg epoxy as solvent after 6 kilograms of butanone and 4 kilograms of Virahols mixing, stir the dissolving that promotes epoxy resin; Get 3 kilograms of titanium dioxides, red iron oxide, graphitized carbon black or organic red in pigment; Get in the methyl alcohol that 2.5 kilograms of glyoxal ethylines are melted to 2.5 kilograms as solidifying agent.Above-mentioned filler and pigment are joined in the epoxy resin solution of dissolving, grind and filter and obtain coating, when coating is used, above-mentioned 5 kilograms of solidifying agent are joined in above-mentioned 95 kilograms of coating, stir, be sprayed directly into the equipment surface, carry out the secondary spraying after half an hour, dry and get final product.

The coating made by the method can reach following index:

1, solid content: the quality solid content reaches 88%, and the volume solid content reaches 74%;

2, hardness: 6H;

3, snappiness: 1 grade;

4, sticking power: pull open method, can reach 14Mpa;

5, thermotolerance: (149 ± 2) ℃, 12h light discolouration;

6, salt water resistance: immerse 30d in 3%NaCl solution, sticking power 17Mpa;

7, acid resistance: immerse 90d in 10% sulphuric acid soln, non-foaming, do not ftracture, do not come off;

8, alkali resistance: immerse 20d in 5%NaHO solution, non-foaming, do not ftracture, do not come off;

9, time of drying: surface drying≤4h, do solid work≤24h.

Following table is the performance comparison of the heavy anticorrosion ceramic pain of the described high abrasion of the embodiment of the present invention and traditional abrasion resistant anticorrosive paint:

As can be seen from the above table, use the heavy anticorrosion ceramic pain of embodiment of the present invention high abrasion than using the required spraying number of times of traditional abrasion resistant anticorrosive paint significantly to reduce, and sticking power, hardness, life-span and solid content all are significantly improved.

The present invention is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present invention; no matter but do any variation on its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection scope of the present invention.
